G. Upper Collector Box and Inducer Housing (Unused)
Drain Connections
1. Upper collector box drain connection
Attached to the UPPER collector box drain connection is a
factory-installed corrugated, plugged tube (blue and white
striped label). This tube is plugged to prevent condensate
leakage in this application. Ensure this tube is plugged.
NOTE: See Fig. 6 or 7 or tube routing label on main furnace door
to check for proper connections.
2. Upper inducer housing drain connection
Attached to the UPPER (unused) inducer housing drain
connection is a cap and clamp. This cap is used to prevent
condensate leakage in this application. Ensure this connec-
tion is capped.
NOTE: See Fig. 6 or 7 or tube routing label on main furnace door
to check for proper connections.
H. Condensate Trap Freeze Protection
Refer to Condensate Drain Protection section for recommenda-
tions and procedures.
III. DOWNFLOW APPLICATIONS
In a downflow furnace application, the blower is located above the
burner section, and conditioned air is discharged downwards.

A. Condensate Trap Location
The condensate trap must be removed from the factory-installed
blower shelf location and relocated in selected application location
as shown in Fig. 2, 8, or 9.
To relocate condensate trap from the blower shelf to desired
location, perform the following:
1. Remove 3 tubes connected to condensate trap.
2. Remove trap from blower shelf by gently pushing tabs
inward and rotating trap.

3. Remove casing hole filler cap from casing hole. (See Fig. 2,
7, or 8.)
4. Install casing hole filler cap into blower shelf hole where
trap was removed.
5. Install condensate trap into desired casing hole by inserting
tube connection stubs through casing hole and rotating until
tabs snap into locking position.
B. Condensate Trap Tubing
NOTE: See Fig. 8 or 9 or tube routing label on main furnace door
to check for proper connections.
Relocate tubes as described below.
1. Collector Box Drain Tube
a. Remove factory-installed plug from LOWER collector
box drain tube (blue and white striped label).
b. Install removed clamp and plug into UPPER collector
box drain tube (blue label) which was connected to
condensate trap.
c. Connect LOWER collector box drain connection to
condensate trap.

(Right-Hand Trap Installation)
(a.) Connect LOWER collector box drain tube
(blue and white striped label) to condensate
trap. Tube does not need to be cut.
(b.) Clamp tube to prevent any condensate leakage.
(a.) Install drain tube coupling (factory-supplied in
loose parts bag) into collector box drain tube
(blue and white striped label) which was pre-
viously plugged.
(b.) Connect larger diameter drain tube (factory-
supplied in loose parts bag) to drain tube
coupling, extending collector box drain tube
for connection to condensate trap.
